VALVE.

Application filed March 17, 1922. Serial No. 544,405.

T 0 all whom it may concern: a

Be it known that I, CHARLES VITEK, a citizen of the Republic ofCzechoslovakia, residing at Maywood, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Valves, of whichthe following is a specification.

This invention relates to valves and has particular reference to thattype of valve which is adaptable for use as a compression pet cock, sotermed, or as an exhaust valve. It is also adaptable for use inconnection with any fluid such as air, gas, or water and may be readilyemployed as a priming cup valve for internal combustion engines.

his the object of this invention to provide a valve of the aforesaidcharacter and one which will be not only simple in construction butpositive in operation.

With these and other objects in view my invention consists in the novelconstruction, combination and relative position of the parts and membershereinafter described and shown in the accompanying drawings, andparticularly pointed out in the appended claim.

Referring to the drawing in which like reference characters indicatelike or corresponding parts:

Fig. 1 is an elevation of a valve in open position embodying myinvention, and Fig. 2 is a vertical cross section of same taken on line22 of Fig. 3.

Fig. 3 is a plan view of the valve in open position.

Referring to the illustrations, my irnproved valve here shown comprisesa stem 10 which is provided with threads 11 for connection purposes witha pipe, tank, engine cylinder or any other apparatus where found useful.The upper portion of the stem 10 is formed with a slightly enlarged head12. An interior passage 13 extends through the head 12 and stem 10 andis disposed at an angle to the vertical or central axis AB of the valvein a way that its lower end is approximately on the center of the axisAB and its upper end eccentric thereof, see Fig. 2.

The head 12 is provided with threads 14 which are preferably cut on arelatively small pitch to insure a fluid tight contact for the cup cap15 which consists of an annular cup 15 and a lower interiorly threadedportion 15 separated from the upper cup portion by the horizontal wall15 which is provided with an opening 16 located eccentrically to thevertical axis A-B and on a radius therefrom to align or register withthe interior passage 13 when the valve is in open position as shown inFigs. 2 and 3. It is obvious that when the valve is in open position asshown in Fig. 2, there will be a slight space 1'7 between the groundunderside or face of the wall 15 and the top face of the raised wall12*, bothof which surfaces are ground or faced for contact when the cap15 is turned to the closed position.

It is also obvious that when the valve cap contact with the smallannular raised in 5 tegral portion 12 so that the passage 13 is closedwithin the cap 15.

If desired, the head 12 can be arranged with a pin stop 18 projectingunder the cap 15 and an integral lug 15 can be cast to the under edge ofthe cap 15 to provide a positive stop for alignment of the .opeuin l6and passage 13 when the lug 15 an stop 18 contact as in Figs. 1 and 3.

Due to the raised annular integral surfaced wall 12*, a space 17 isprovided between the under face of the wall 15 and the top of the head12, even when the cap is in closed position in tight frictional eng'agement with the surfaced wall 12 raised wall 12 eliminates thesurfacing of the entire top of the head 12 and provides a space 17 forsmall dust or the like, which might otherwise affect the air tightclosing of the valve.

I claim:

A valve comprising a pair of screw-connected members, one of saidmembers having a lateral wall and an opening eccentric to its axis ofrotation, the other member This Y f if 1,511,692

7 .iaving' a passage disposed diagonally to the underside of saidlateral wall to close its perpendicular axis, the upper end of said theupper end of said passage.

passage being adapted for alignment with In witness whereof, I havehereunto sub- 1. said opening, a relatively small raised surscribed myname this 15th day of March, face portion of said second-mentioned mem-1922;

her surrounding said upper end; of said passage arranged forfrictionaleontact with CHARLES VITEK.
